Question

If the number of hours for which a labourer works is x and y are his wages (in rupees) and y = 2x − 1, then draw the graph of work-wages equation. From the graph, find the wages of the labourer if he works for 6 hours.

Answer 1

The values of x and y satisfying the given equation y = 2x − 1 are:

x	0	1	2	3	4
y	–1	1	3	5	7

The graph of the given equation y = 2x − 1 is as follows:

In the graph, a point A(6, 11) lies on the line.

So, at x = 6, y = 11

Hence, the wages of the labourer if he works for 6 hours is Rs 11.
